China Wholesale Double beam IR spectrophotometer Manufacturers – LADP-2 Experimental System of Pulsed NMR – Labor Detail:

Experiments

1. Understand the basic physical theory and experimental configuration of a PNMR system. Learn to explain related physical phenomena in PNMR using classical vector model.

2. Learn to use signals of spin echo (SE) and free induction decay (FID) to measure T₂ (spin-spin relaxation time). Analyze the influence of magnetic field homogeneity on NMR signal.

3. Learn to measure T₁ (spin-lattice relaxation time) using reverse recovery.

4. Qualitatively understand the relaxation mechanism, observe the effect of paramagnetic ions on nuclear relaxation time.

5. Measure T₂ of copper sulfate solution at different concentrations. Determine the relationship of T₂ with the change of concentration.

6. Measure the relative chemical displacement of the sample.
